Abstract
The objective of this study is to evaluate the performance of variable and fixed speed
chillers in their current production environment using operational data sets from
multiple chillers. The study seeks to determine the actual contribution to efficiency
and conditions for efficiency of both variable and fixed speed chillers. The analysis
also develops performance prediction models for both types of chillers under various
operating conditions and in doing so demonstrates that variable speed chillers have
significantly outperformed initial energy savings estimates. Lastly, the results
demonstrate that chiller performance and potential energy savings are relatively predictable
under most operating conditions, helping to verify operators’ current understanding
of plant operation.
